Failedto upgrade Oracle Cluster Registry configuration
在安装CRS时,在第二个节点执行./root.sh时,出现如下提示,我在第一个节点执行正常.请大虾指点一些,不胜感激!谢谢!

错误原因:
是因为安装crs的设备权限有问题,例如我的设备用raw来放置ocr和vote,此时要设置好这些硬件设备以及连接的文件的权限,下面是我的环境:
[[email protected] oracrs]#
lrwxrwxrwx 1 root root 13 Jan 27 12:49 ocr.crs -> /dev/raw/raw1
lrwxrwxrwx 1 root root 13 Jan 26 13:31 vote.crs -> /dev/raw/raw2
chown root:oinstall /dev/raw/raw1
chown root:oinstall /dev/raw/raw2
chmod 660 /dev/raw/raw1
chmod 660 /dev/raw/raw2
其中/dev/sdb1放置ocr,/dev/sdb2放置vote.
[[email protected] oracrs]# service rawdevices reload

           /dev/raw/raw1 -->   /dev/sdb1
/dev/raw/raw1: bound to major 8, minor 17
           /dev/raw/raw2 -->   /dev/sdb2
/dev/raw/raw2: bound to major 8, minor 18
Done
然后再次执行就ok了.

Oracle gave me a patch that allowed us to format the OCR and voting disk. Now the problem may just be I need to run root.sh on node1 or wipe both clean and start fresh.
Devices formatted, now we need to get the CRS daemon up and running on both nodes..

I think whats needed is a clean install.

在 node1 上执行：/opt/ora10g/product/10.2.0/crs_1/root.sh; 在 node2 上执行：/opt/ora10g/product/10.2.0/crs_1/root.sh; 

通常在最后一个节点执行root.sh时会遇到错误，就我们的情况而言当然就是node2~~

提示：一般常见的错误有如下三种：

A).如果你碰到了这个错误：
/opt/ora10g/product/10.2.0/crs_1/jdk/jre//bin/java: error while loading shared libraries:  libpthread.so.0: cannot open shared object file: No such file or directory
可以按照如下方式解决：
===============================
修改vipca文件
[[email protected] opt]# vi /opt/ora10g/product/10.2.0/crs_1/bin/vipca
找到如下内容： 
       Remove this workaround when the bug 3937317 is fixed 
       arch=`uname -m` 
       if [ "$arch" = "i686" -o "$arch" = "ia64" ] 
       then 
            LD_ASSUME_KERNEL=2.4.19 
            export LD_ASSUME_KERNEL 
       fi 
       #End workaround
在fi后新添加一行：
unset LD_ASSUME_KERNEL
以及srvctl文件
[[email protected] opt]# vi /opt/ora10g/product/10.2.0/crs_1/bin/srvctl
找到如下内容：
LD_ASSUME_KERNEL=2.4.19
export LD_ASSUME_KERNEL
同样在其后新增加一行：
unset LD_ASSUME_KERNEL
保存退出，然后在node2重新执行root.sh
当然，既然我们已经知道了有这个问题，建议最好在node2执行root.sh之前，首先修改vipca。
其实同时需要你改的还有$ORACLE_HOME/bin/srvctl文件，不然等装完数据库之后，srvctl命令也是会报这个错误地。要知道srvctl这么常用，如果它执行老报错，那可是相当致命啊。不过呢你现在才安装到crs，离create db还远着呢，大可以等到创建完数据库，待到需要管理时再修改该文件。

B).如果你碰到了这个错误：
The given interface(s), "eth0" is not public. Public interfaces should  be used to configure virtual IPs.
解决方式如下：
==============================
图形界面上运行$CRS_HOME/bin/vipca，手工重新配置rac1-vip和rac2-vip。
[[email protected] opt]# xhost +
[[email protected] opt]# /opt/ora10g/product/10.2.0/crs_1/bin/vipca
按照提示点击下一步
点击finish即可vipca开始自动配置
全部配置完成之后，点击exit退出操作窗口。

C).如果你碰到了这个错误：
Error 0(Native: listNetInterfaces:[3]) 
 [Error 0(Native: listNetInterfaces:[3])]
解决方式如下：
===============================
[[email protected] bin]# ./oifcfg iflist
eth1  10.10.17.0
virbr0  192.168.122.0
eth0  192.168.100.0
[[email protected] bin]# ./oifcfg setif -global eth0/192.168.100.0:public[[email protected] bin]# ./oifcfg setif -global eth1/10.10.10.0:cluster_ interconnect
[[email protected] bin]# ./oifcfg getif
eth0  192.168.100.0  global  public
eth1  10.10.10.0  global  cluster_interconnect
然后在视窗界面重新执行vipca即可，如上b例中所示。
